Dunkirk is one of the most established names in hydronic heating. Their reputation has been built over the years by ingenious design and perpetual innovation. The H2O storage tank is a great addition for hydronic heating systems. Capable of storing 40 gallons of hot water, the H2OST40DK helps with short-cycling, unbalanced water temperatures, and insufficient DHW production. Using hot water from a storage tank for low volume demands saves wear and tear on your boiler or water heater. With high volume demands, the storage tank can enhance your DHW output by making sure that you always have enough hot water for your applications. The stored hot water can also be used in mixing applications to even out water temperatures. Whether you are supplementing older equipment, or designing a hydronic system from the ground up, the H2O storage tank will streamline your hot water applications.

Product Features

Amazing DurabilityThe H2OST40DK is built to last. H2O storage tanks are wrapped in a thermoplastic jacket to prevent damage while stainless steel construction of the tank prevents damaging corrosion and keeps your water supply clean.

Efficiency-Boosting InsulationStandby heat loss is one of the quickest ways to negate the benefits of a hot water storage tank. Two and a quarter inches of expanded polystyrene insulation bring the H2O's standby loss under a half degree Fahrenheit per hour.
